EMRT Professional SCR, DEF & DPF Emulator – Detroit Diesel GHG14

Direct ACM Replacement for Freightliner & Western Star (DD13, DD15, DD16)

The EMRT Professional Detroit Diesel GHG14 Emulator is a premium recovery solution for the second generation of GHG-compliant Detroit engines. Designed to serve as a direct hardware replacement for the factory ACM (Aftertreatment Control Module), this module provides a total digital synthesis of the SCR, DEF (AdBlue), and DPF systems. It is the definitive solution for eliminating "check engine" lights, torque derates, and the dreaded 5 km/h limp mode on GHG14-equipped trucks.

Key Features

Direct ACM Replacement: This module completely replaces the factory ACM ECU. No need to spend thousands on a new OEM module; simply disconnect the original and plug the EMRT Emulator directly into the factory harness.
Full System Emulation: Digitally manages the entire aftertreatment network, including DEF pump pressure, DPF soot-load logic, and sophisticated NOx correlation.
Plug & Play Integration: Engineered with factory-spec connectors for a secure, moisture-proof connection. No wire cutting or specialised tools are required for installation.
Ruggedised for ANZ Road Trains: Housed in a fully resin-sealed, waterproof casing. Built to withstand the extreme heat and vibration typical of Australian long-haul and heavy-duty vocational applications.
Connector Protection: Includes a factory-spec protective cap for the original ACM harness connector to prevent environmental damage.

Emulated Components

This module provides high-fidelity digital reporting for:

ACM ECU (Aftertreatment Control Module).
Upstream & Downstream NOx Sensors.
DEF Dosing Pump & Pressure Sensors.
DEF Level & Quality (Concentration) Sensors.
DPF Differential Pressure & Soot Load Signals.
Multi-point Exhaust Temperature Sensors.

Compatible Engines & Models

Optimised for Detroit Diesel GHG14 (2014–2017) Platforms:

Engines: DD5, DD8, DD13, DD15, and DD16 GHG14 variants.
Freightliner Models: Cascadia (Gen IV), M2 106/112, Columbia, Coronado, 122SD, 114SD, and Business Class.
Western Star Models: 4700, 4800, 4900, and 5700 series.

Installation Requirements

CRITICAL: Pre-Installation Service Routine

To ensure the Engine Management System (MCM) synchronises correctly with the emulator, the following steps must be followed:

Reset: Perform the "DPF Ash Accumulator" service routine using diagnostic software (e.g., Detroit Diagnostic Link) before connecting the emulator.
Replace: Disconnect the factory ACM and install the EMRT Professional Emulator in its place.
Protect: Fit the included protective cap to the factory connector.
Exhaust: To prevent turbocharger damage, the physical DPF filter must be modified (drilled/hollowed) or replaced with a standard muffler.
